Revision Total Hip Replacement

Although total hip replacement is a durable and successful procedure but it can be subject to various forms of mechanical or biological failure. This failure may need a re-operation of the hip replacement which is called a revision surgery.

A hip revision surgery involves the replacement of the worn out, loose, painful, infected or failed prosthesis with a new hip implant.

The goals of surgery are to relieve pain, improve function, and enhance overall quality of life.

Reasons for Hip Revision Surgery

A patient may need hip revision surgery due to the following reasons:

  • Worn out prosthesis

  • Bone loss around the prosthesis

  • Loose prosthesis

  • Unstable prosthesis with recurrent dislocation

  • Infected prosthesis

  • Repetitive dislocation of a hip replacement

  • Mechanical failure

  • Breakage of prosthesis

  • If the initial hip replacement surgery is performed at a young age

Procedure of Hip Revision Surgery

Revision surgery is quite similar to primary hip replacement but it is more complicated and challenging procedure that takes longer and is unique for every patient. The procedure may take two to four hours and a variety of techniques may be used in the procedure including:

  • Removal or exchange of the old prosthesis

  • Preparation of the bone for the new implant

  • Bone grafting in areas of bone loss

  • Implantation of the new prosthesis

Benefits of Hip Revision Surgery

  • Eliminates or diminishes pain

  • Improves joint function & mobility

  • Increases strength and coordination of the torso and leg

  • Improves the appearance of the hip and leg

  • Incredibly improves the quality of life of the patient

  • Improves the patients ability to walk and perform regular activities

  • Prevents new dislocation of hip joint

Risks of hip revision surgery

Although revision surgery is a safe procedure but it may cause some complications like:

  • Respiratory or cardiac malfunction due to anaesthesia

  • Infection

  • Injury to nerves and blood vessels

  • Fracture

  • Weakness, stiffness or instability of the joint

  • Joint pain
